Umm... MMDF has nothing to do with Sendmail 8.9.3, as far as I know.  I've
been alpha/beta testing Sendmails since 8.9.0 and don't remember any MMDF
in there.

Are you sure that this is not an MMDF binary installed as /usr/lib/sendmail
as a submission agent, to provide compatibility with scripts and programs
that think /usr/lib/sendmail can be used to submit mail?
